To manage severe anemia, usually caused by splenic sequestration (dangerously enlarged spleen) or aplasia (halting of red blood cell production, most often caused by parvovirus). Transfusions are generally not required for mild or moderate anemia.

Surgical measures to prevent reflux can be considered if other measures fail or complications occur such as bleeding, recurrent stricture, or metaplasia (abnormal transformation of cells lining the esophagus), which is progressive.
This process is called intestinal metaplasia because the specialized columnar cells are similar to the lining of the intestine. Damage to the lining of the esophagus causes the cells to change.
